Hi, this is a bit off topic.

I'm learning SPARC assembly and UltraSPARC architecture. I would like to 
create a small flat binary file with gcc and then load and execute it from 
openboot. The idea is to execute privileged instructions and mess about with 
system registers which are not accessable from userland.

Does anyone know how this can be done on Ultra 10? I think on powerup the 
processor is in RED state, is there a way to execute a few assembly 
instructions that print a message on console? Is there a way to interact with 
openboot firmware?
